Holosun HS507C-X2 ACSS Vulcan Red Dot Sight

This is the Primary Arms exclusive build of the HS507C-X2, and the reticle is the difference. The ACSS Vulcan wraps a large 250 MOA ring around a 10 MOA center chevron, so your eye catches the sight picture on the draw even when the dot is not centered in the window, and the chevron gives a defined aiming point once the gun settles. Shooters who lose time hunting for a small dot tend to get along with it immediately.

The rest is standard 507C-X2. A solar panel backs up the battery and keeps the reticle lit if power runs out, and Shake Awake turns the optic on when the pistol moves and puts it back to sleep when it sits. The CR1632 loads from a side tray, so a battery change does not cost you zero, and Holosun rates it at 20,000 hours on setting six. The RMR footprint fits most optics ready slides and adapter plates.
